A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1166 M standard sodium hydroxide solution. He takes a 25.00mL sample of the original acid solution and diluted it to a 250.0mL. Then, he takes a 10.00mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 12.52mL of the standard solution. What is the concentration of the original sulfuric acid solution?  concentration:_____M
